A suspected suicide attack has killed at least 28 people and wounded nearly 100 others in the Turkish town of Suruc near the Syrian border BBC reports.
The blast occurred in the garden of a cultural centre at about 09:00 GMT, the interior ministry said.
Hundreds of young people were staying there to assist in rebuilding work in the nearby Syrian town of Kobane.
Turkish officials have said initial evidence indicates it was a suicide attack by the Islamic State (IS) group.
Turkey’s President Recep Tayyip Erdogan has condemned the bombing and described it as “an act of terror”.
Suruc houses many refugees who have fled the fighting in Kobane between IS militants and Kurdish fighters.
IS overran the town in September last year, but it was retaken by Turkish forces in January.
The district governor of Suruc, Abdullah Ciftci, said:
“The fact that it is a suicide attack increases the possibility that IS is responsible.
“We think the attacker was a woman.
“Preliminary findings show that she was acting on her own,” he told BBC Turkish.
A statement from the Turkish interior ministry said: “We call on everyone to stand together and remain calm in the face of this terrorist attack which targets the unity of our country.”
A local journalist, Faruk Baran, told BBC Turkish that there was panic in Suruc after the attack, with shopkeepers closing up for fear of a second attack.
